I believe that there was a guy awhile back that was buying it at Walmart and dumping it straight into his tank. No mix whatsoever. He was from Wales or something like that where the veggie oil from the shelf was actually cheaper than diesel.

The forum mentioned earlier in this thread is a very fun place to browse. There is a story there about a guy who took a car into Mexico and only used WVO. He'd go until he'd run out and then start begging grease. It was a hugely read thread and covered 2-3 weeks on his journey.
